About 09BW8ZX
09BW8ZX is the ICD-10-PCS code for a excision procedure on the right sphenoid sinus using a via natural or artificial opening endoscopic approach (qualifier: diagnostic). In ICD-10-PCS, excision means cutting out or off, without replacement, a portion of a body part.
In plain terms, this corresponds to closed [endoscopic] [needle] biopsy of nasal sinus, the ICD-9-CM procedure title it maps to (22.11).
For a different body part, codes include 09B38ZX (right external auditory canal), 09B48ZX (left external auditory canal), 09B58ZX (right middle ear), 09B68ZX (left middle ear), 09B78ZX (right tympanic membrane), 09B88ZX (left tympanic membrane) and 20 more.
The same procedure with a different approach is coded 09BW0ZX (open), 09BW3ZX (percutaneous) and 09BW4ZX (percutaneous endoscopic).
It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.
It was added in FY2018, effective October 1, 2017.
